HS Code for Molybdenum hydroxide

Molybdenum hydroxide is classified under HS code 282570. This code is part of Chapter 28, which encompasses inorganic chemicals, precious metal compounds, and rare-earth metals. Specifically, heading 2825 covers hydrazine and hydroxylamine and their inorganic salts, as well as other inorganic bases and other metal oxides, hydroxides, and peroxides. Subheading 2825.70 is dedicated specifically to molybdenum oxides and hydroxides. Molybdenum hydroxide, often existing in hydrated forms or as molybdic acid (which is chemically treated as a hydrated oxide), is used extensively in chemical synthesis, as a catalyst in the petroleum industry, and in the production of pigments. The classification is straightforward as it is based on the chemical composition of the substance as a metallic hydroxide.

Products Included

• Molybdenum(VI) hydroxide
• Molybdenum(IV) hydroxide
• Hydrated molybdenum trioxide (Molybdic acid)
• Molybdenum oxide hydrate
• Technical grade molybdenum hydroxides

Common Misclassification

Molybdenum hydroxide is sometimes misclassified under HS code 2841.70, which is for molybdates. While related, molybdates are salts of molybdic acid, whereas 2825.70 is for the hydroxide or oxide itself. Another error involves HS code 2613, which is for molybdenum ores and concentrates; 2825.70 is only for chemically defined compounds, not raw minerals extracted from the earth.

FAQ

What is the HS code for molybdenum hydroxide?
